The Campaign. HHH Five-time incumbent Will Ferrell must hold off a late charge by unheralded challenger Zach Galifianakis in a nasty (but funny) North Carolina political battle. Rated R.

Diary of a Wimpy Kid: Dog Days. (No Ebert rating) Greg (he’s the hero of these) is on summer vacation with nothing to do. Bet he finds something to do ... Rated PG.

Total Recall.HHH Arnold may be no match for Colin Farrell as an actor, but Farrell’s no match for Arnold as a real-life cartoon character. Advantage Arnold. Rated PG-13.

Step Up Revolution.HH They have now made four of these. A rich girl’s dad wants to develop the neighborhood where her dance-crazed boyfriend likes to hold flash mobs. This is not an original premise. Rated PG-13.

The Watch.HH Ben Stiller and Vince Vaughn apparently think that writing tired, predictable scripts will never fail to produce comedic hits like “Dodgeball” as long as they put themselves in the movie. They are sorely mistaken. Rated R.

The Dark Knight Rises. HHHSee description above.

Ice Age 4: Continental Drift.HH (In standard and digital 3-D with surcharge) I’m not going to pretend like I know what happened in the first three. Surely there are those who do, and for them we present No. 4. Enjoy. Rated PG.

Ted. HHH½ Mark Wahlberg’s wish for his childhood teddy bear to come to life comes true. But this is a Seth MacFarlane film, so Ted is not a well-behaved companion. Rated R.
